This is ready for review :)

Velocity-actions.js was starting to look like an action-store hybrid so I pulled all of the data-processing out into the product-store, leaving the action creator interface a little cleaner. I thought about creating a velocity store (and think this might be something we should think about for the future as we continue to beef up our support for agile workflows), but decoupling velocity from product-store internals is a bit more involved than time allows atm.

CI failure was instant, and I assume related to the recent Wercker changes that we're dealing with elsewhere.

@florapdx CI should work again if you merge in the latest master.

Cool, thanks @khalsah!
